The attitude of the vehicle to maintain a trajectory established by the steering elements, opposing the lateral forces (wind, centrifugal force on bends, etc.). It depends significantly on the tyre characteristics (traction, drift, etc.).

Any force (centrifugal, side wind, effect of hump back road, etc.) operating in the direction of the tyre rotation axle.

The attitude of the vehicle to maintain a trajectory established by the steering elements, opposing the lateral forces (wind, centrifugal force on bends, etc.). It depends significantly on the tyre characteristics (traction, drift, etc.).

It is the wheel that not only supports the vehicle but also gives it a direction because it is connected and can be moved with the drive elements. It may be the drive wheel at the same time.

A sheet of compound impermeable to air, vulcanised inside tubeless tyres. It replaces the inner tube.

It is the internal corner of the bead heel. It rests on the edge of the rim when this has one; e.g. Hump.

The load index represents the maximum load in kilograms that the tyre can bear: the indices and the relevant values in kilograms are reported in special tables.

Distance of the loaded tyre axis from the ground. It corresponds to the free radius minus the deflection.

It describes tyres in which section height (H) and width (C) have a ratio which is lower than 1. E.g. the lowered series 60 indicates a ratio H/C = 0.6
